5 Claims, 2 Drawing Figures PATENTED JAN 30 I975 R m E V m Fla 2 HARLAN R. CARROLL fl/flfli) ATTORNEY TEXTILE NOISE REDUCTION DEVICE BACKGROUND OF THE INVENTION lnterlacing jets have become widely used in recent years for the treatment of industrial and textile yarns both as a twist substitute and for the insertion of bulk or slubs into a yarn. Different types ofjets are used for the various numerous end uses with specific designs having been developed for specific end uses. Certain design characteristics are more suitable for each of the various yarn treatments which can be effected by such jets. However, all of these jets have in common two basic characteristics, that is: l) the jets are operated by means of high pressure fluids; and 2) such operation produces a high noise level. Such noise levels are dependent to a great extent upon the fluid pressure at which the jet is operated, the design thereof and the fluid utilized.

It is an object of the present invention to provide means for reducing the sound level of such jets to an acceptable level.

lt is another object of the present invention to provide an interlacing jet for textile purposes with substantially reduced noise level, which reduction does not interfere with the efficiency of'such interlacers.

These and other objects of the invention will become apparent to those skilled in the art from the description ofthe invention which follows.

THE lNVENTlON In accordance with the invention, a textile yarn treating apparatus is provided comprising a pressurizedfluid yarn treating jet, said jet being composed ofa yarn confining passageway and yarn guide means thereto, said passageway having at least one pressurized fluid exhaust port therein directed for disruption of said yarn in said passageway by said fluid, the improvement comprising an enclosure for said jet and guide means, said enclosure forming a chamber substantially surrounding said jet (except for yarn entry and exit apertures), said chamber having at least one fluid exhaust port therein, said enclosure walls being covered with sound absorbing material.

The described apparatus is designed to provide sufficient fluid exhaust capabilities from the yarn interlacer device without interfering with the operability thereof, such as ease of yarn ingress and egress. Further, the enclosure and exhaust ports freely exhaust the pressurized fluid from the jet and chamber area without creating interfering back pressures in the chamber or jet, which pressures would tend to change with the operation ofthe jet.

DETAILS OF THE INVENTION The apparatus of the present invention is more fully described by reference to thedrawing in which:

FIG. 1 is an isometric view of a-preferred jet enclosure and exhaust ports and FIG. 2 is a further isometric view of the apparatus of FIG. I in the open position illustrating the positioning of an interlacing jet and guide means therein in relationship to the enclosure.

Jets of the present invention are normally operated under various pressurized fluids, particularly ambient air, heated air or steam. As such, various pressures ranging from relativelylow to moderately high are utilized, depending upon the requirements of the particular jet, the type of treatment directed against the yarn, yarn travel speed and the like considerations. As such, pressures ranging as low as about pounds per square inch gauge to 150 or more pounds per square inch gauge are often utilized, but more often, pressures of about 20 60 p.s.i.g. are utilized.

The pressurized fluid is conveyed to the interior of the passageway through which the yarn travels and is exhausted in one or more exhaust ports into the passageway either directly at the yarn, at an angle thereto, or tangentially against the yarn. The basic concept is to create fluid forces in the passageway through which the yarn is traveling to thereby disrupt the smooth passage of the yarn thereby interlacing it, bulking it, crimping it, entangling it,slubbing it or the like, depending upon the fluid used, the temperature and pressure thereof and the yarn tensions as it is fed and withdrawn from the passageway. Various designs are known in the art such as double-opposed jets, tangentially angled jets and the like, all of which create a turbulent fluid flow thereby disrupting and entangling the yarn. The pressurized fluid is exhausted from the passageway thereby creating substantial exhaust noises ranging from about decibels to well in excess of 1 l0 decibels at the higher pressure levels.

Referring more particularly to FIG. 2, yarn interlacing apparatus 10 comprises hinged sidewalls l2 and 14 which open for access to interlacing jet l6. Sidewall 14 has positioned thereon fluid exhaust ports 18 and 20, which are connected to mufflers 22 and 24. Sidewalls 12 and 14 are covered on the interior portion thereof with sound insulating material 26, such as foamed polyurethane,fibers, batting and the like sound absorbing materials which are generally characterized as high porosity low density structures. In the end walls 28 and 30 of yarn texturing apparatus 10 are located yarn guide means 32 and 34. Yarn guides 32 and 34 are preferably made of low friction material such as ceramic or other yarn guiding material such as various hardened metals commonly used for yarn guides. Additionally, end walls 28 and 30 are covered on the interior portion thereof with sound absorbing materials.

lnterlacing jet 16 comprises yarn passageway 36 through which yarn travels from guide 32 through passageway 36 and exits from yarn treating apparatus and through guide 34. Within yarn passage 36 is at least one fluid exhaust port through which high pressure fluid, particularly steam or air, is exhausted so as to form a turbulent zone within passageway 36, to thereby disrupt and entangle the yarn or otherwise treat it in accordance with well known yarn fluid treatment techniques. The fluid for the jet is conveyed through the body in interlacer l6 and is connected to high pres sure fluid lines (not shown) on the back side of interlacing jet 16.

The invention will be more clearly exemplified by the following examples which illustrate certain embodiments of the present invention. lt should be noted, however, that such exemplification merely illustrate certain preferred embodiments of the invention and is not intended to be limiting thereof.

EXAMPLE The apparatus illustrated in FIGS. 1 and 2 was operated by stringing therethrough a 1300/] 36 yarn to be interlaced to form a compacted yarn. The interlacing yet was operated at various air pressures. The noise level therefrom was measured both without the noise abatement apparatus and with the noise abatement apparatus. The following results were obtained.

Open Enclosed Air Pressure Jet .Iet p.s.i.g. 60 l02 78 p.s.i.g. 80 W3 87 p.s.i.g. I I06 94 An examination of the yarns treated by the jet when operated with the noise abatement device compared to the open jet indicated that the back pressures developed in the enclosed jet were insufficient to noticeably affect the treatment ofthe yarn.

it will be noted that the noise reduction, particularly at the 60 p.s.i.g. pressure, which is a normal operating pressure, reduces the decibel rating to tolerable levels. Additionally, it should be noted that decibels are measured on a logarithmic scale, thus a l decibel increase or decrease in the noise level represents about 26 percent change in noise intensity. As such, the reduction in jet noise is a reduction of many times the audible noise level.

Although the invention has been described more particularly with interlacing jets, it will be recognized that other jets utilizing fluid pressures to crimp, entangle, slub or otherwise treat yarn can be muffled in the same manner as that illustrated herein. As such, it is intended that the present invention is not to be limited to the specific exemplified embodiment but only by the accompanying claims.

What is claimed is:

1. In a textile interlacing apparatus comprising a pressurized fluid yarn interlacer, said interlacer being composed of a yarn confining passageway and yarn guide means thereto, said passageway having at least one pressurized fluid exhaust port therein directed for impingement against a yarn in said passageway, the improvement comprising an enclosure for said interlacer and guide means, said enclosure substantially forming a noise suppressing chamber with at least one fluid exhaust port therein, said interior enclosure walls being covered with sound absorbing material, said fluid exhaust port having muffler means connected thereto.

2. The apparatus of claim 1 wherein two exhaust ports are used with muffler means connected thereto.
